S-95893A163 Length 8 mm Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ensuring long-term reliability in various environments.
• Enhanced torque transmission and reduced cam-out thanks to the T5 Torx drive, providing secure installation and minimizing tool slippage.
• Secure, flush-mount fastening with a standard flat head and 90° countersink angle, ideal for clean finishes in plastic assemblies.
• Strong, permanent threads in plastic materials achieved through TRS thread forming design, eliminating the need for tapping and reducing assembly steps.
• Full-length threading for maximum grip across the entire 8mm length, distributing load evenly and improving joint integrity.
• Precision compatibility with No. 55 drill bits, ensuring accurate hole sizing and reducing the risk of material damage during installation.
• Environmental and regulatory compliance with RoHS 3 and REACH standards, supporting sustainable and safe manufacturing practices.

Professional Applications & Engineering Value

These M1.6 metric tapping screws are specifically engineered for plastic fastening applications, where traditional threaded fasteners may strip or fail. Made from 18-8 stainless steel, they resist corrosion and maintain integrity in humid or chemically exposed settings, reducing maintenance costs. The TRS thread forming design displaces plastic material to create strong, load-bearing threads without chips, minimizing stress cracking in brittle plastics. With a T5 Torx drive and flat head profile, they enable high-torque installation and sit flush for streamlined assemblies in electronics, automotive trim, and consumer goods. This combination of material durability and precision threading solves common issues like loosening under vibration and simplifies production with compatible No. 55 drill bits.

Specification Summary & Compliance

This screw features an M1.6 metric size with an approximate thread pitch of 0.67 mm and fully threaded, right-hand design for consistent engagement. It adheres to standard flat head dimensions with a 90° countersink angle and is manufactured to precise tolerances suitable for thread forming applications. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it meets strict environmental and safety standards for industrial use.
